Description

The manufacture method of globular glass manufacturing installation and globular glass

Technical field

The present invention relates to make the globular glass manufacturing installation that is used for the globular glass that uses as preliminary working material or lens etc. and the manufacture method of globular glass, described preliminary working material be used for by the precision pressure moulding obtain DVD, CD, CD (MO) etc. optically read lens, be with photographic camera mobile telephone with lens, be used for optical communication with optical elements such as the lens of lens or opticinstrument etc. or prisms.

Background technology

In recent years, in order to cut down manufacturing cost, optical elements such as lens are made by following precision pressure moulding gradually: heating glass preliminary working material also makes that it is softening, carry out pressure forming with the metal pattern with high-precision molding surface, has omitted the grinding after the moulding, grinding step and can directly obtain optical element such as lens.For example, the mobile telephone of making the optically read lens of DVD etc., band photographic camera by the precision pressure moulding with the light of lens or the photorectifier that uses in fields such as optical communications or laser diode and optical fiber in conjunction with small lens such as lens the time, use small spherical preliminary working material.In addition, also use sometimes small globe lens as above-mentioned light in conjunction with lens etc., this is used as above-mentioned small spherical preliminary working material or small spherical lens etc. with regard to needing the globular glass about the about 0.8mm of diameter～about 2.4mm.

As the method for producing the preliminary working material with low cost in batches, generally be make the glass that in glass melting furnace, melts flow down from flowing out ozzle, with someway the glass that flows down being cut apart and with its refrigerative method; At this, as cutting apart, make the method for the frit block of small particle size from the effusive glass of front end that flows out ozzle, melten glass by the smelting furnace fusing is flowed out with Continuous Flow from flowing out ozzle, flow by adjusting melten glass, flow velocity, viscosity etc. make the melten glass that flows down with Continuous Flow be subjected to surface tension effects and are changed to the glass block that is the droplet-like that row fall halfway.And, known have will be the glass block that falls of row receive in the intercepting basin and the method (for example, opening flat 9-235122 communique) that will reclaim as the frit block of preliminary working material or lens etc. with reference to the spy.

Open in the manufacture method of the frit block of institute's publicity in the flat 9-235122 communique above-mentioned spy, with the effusive melten glass of Continuous Flow by in flowing down process, the wire drawing between melten glass being cut off the glass block be changed to droplet-like by surface tension, but, because 2 glass block that adjoin each other this moment are up and down involved by surface tension each other, so mutual falling velocity produces difference, be a row whereabouts midway, 2 glass block can come in contact or collide, are combined into 1 glass block each other sometimes.

And, bonded glass block so again, according in conjunction with the time temperature and viscosity and be combined into only a part of combination in 1 or 2 glass block fully, thereby become different shape, the frit block weight and the shape that obtain are inhomogeneous.

In addition, even be combined into 1 glass block again, owing in inside, produce texture sometimes, so can not be used as optical element.

And then, even for bonded glass block more not, if since in dropping process up and down the glass block of adjacency contact each other then can stay scar from the teeth outwards, so can not be used as optical element.

As known from the above, must the glass block of adjacency up and down each other again in conjunction with or contact before glass block is reclaimed, though can avoid the problems referred to above point by the distance of fall that shortens glass block, if must reclaim the glass block of the condition of high temperature but distance of fall is short, cause ftractureing, glass block must be received in the problem that reclaims among the pyritous wet goods because of the thermal shocking of glass block so produced in order to prevent.Particularly, glass block at the soft state that high temperature and viscosity is lower is received under the situation about reclaiming among the pyritous wet goods, makes the glass block distortion make the shape of the frit block that the obtains uneven problem that becomes thereby produced impact when colliding with liquid level; In addition, under situation about reclaiming with pyritous oil reception glass block, for being used as preliminary working material or optical element, glass block need carefully carry out the cleaning of glass block, cleaning needs time and cost, and can be created in the problem that injures the surface of glass block in the cleaning process easily; And then, when receiving the pyritous glass block, also have the problem of the oily security aspect that might catch fire with pyritous oil.

In addition, when glass block is used as the preliminary working material that is used for the precision pressure moulding, even, can not be used as optical element to causing weight preliminary working material inhomogeneous or produced texture in inside to carry out the precision pressure moulding in conjunction with waiting again because of above-mentioned; If the uneven preliminary working material of shape is carried out the precision pressure moulding, then might produce the thickness generation deviation of the undesirable condition (shrink mark) of part depression on surface of moulding product or moulding product and produce the undesirable condition of inclined light shaft and can not be used as optical element; If have the preliminary working material of scar to carry out the precision pressure moulding to the surface, the glass surface of the part in the time of then might being created in moulding around scar or the scar be folded and enter into that glass inside, glass solidify under this state and bad (folding line) situation that causes or gas to enter into glass from the part of scar inner and at the undesirable condition of the small bubble of the inside of moulding product generation, thereby can not be used as optical element.

On the other hand, publicity has the manufacturing technology (for example opening the 2003-104744 communique with reference to the spy) of following spheroid glass: for remaining on the melten glass that keeps in the container, on one side this melten glass is applied vibration and be gas phase by the aperture on the part that is located at above-mentioned maintenance container on one side and discharge and forms the glass drop, while make this glass drop be gas phase or solidify the liquid phase whereabouts.
